Hey guys. not looking for some big detailed response, just want a quick question answered. There is a motor out of some Volkswagen (1.8l) sitting on the shop floor and it has the stock turbo and all of the piping etc. still on it. could i build a super budget turbo setup on my ef hatch (D16a6)? it's a stock block, so ~7psi and whatever necessary mods (injectors?). can it be done for a cheap turbo set up? just looking for a little get up and go when i need it. Thanks, Dylan.

sounds like you got a turbo... still gonna need a lot of other things...

piping, (FMU, or engine mgmt) oil lines, injectors, etc.

What's your definition of cheap? lol

kyden

you could probably run way more than 7 psi with that turbo... only problem with that turbo is its got weird flanges.

Alright, the turbo is out of a 2002 bug, and i believe it is a k03, with these specs. what kind of performance can i expect out of it?
Compressor Air inlet 1.75"
Compressed Air Outlet 2"
Exhaust Outlet 2.5"
Turbine Housing Flange Standard K03
Exhaust Outlet 3-bolt
Cooling Oil and Water Cooled
Working Pressure 6-25 PSI
Compressor Wheel .36A/R
Compressor Minor 36 mm
Compressor Major 50 mm
Compressor Trim 52.8
Turbine Wheel .87A/R
Turbine Minor 40.5mm
Turbine Major 45mm
Turbine Trim 81.9
Works for Audi A4, Passat with 1.8T turbo engine

Also, with the air outlet being 2", does that mean i have to use 2" piping/intercooler?

Thanks guys, both very valuable posts lol j/k

Alright, i found a lot of info on this after i found the model name. it seems the general consensus is that this turbo is very small, and chokes the 1.8 @~5k. Most people who were looking to use this were declined by the lack of top range and the difficulty of finding the flange. However, I have the entire motor, so i have the flange. And since the stock redline is 6.5k, i think if i crank up the boost, put a big exhaust on, and having smaller displacement it should be ideal for a daily driver and only run out of breath right when I'm ready to shift. I'm mainly looking to get some experience with turbo stuff, and give the old hatch a little pep. Apparently the k03 is also internally wastegated, so that saves even more fab work. What do you guys think?

Since you aren't planning on going big, it should be fine. You're gonna have to do some fab work to make a turbo manifold with that flange. The spool on it will be nice and quick too.

SovXietday

You're going to need to find a manifold that has that flange, which isn't going to be easy. Or you can make it yourself, whatever you decide.

Um, also something to note, I know you think since we have smaller displacement it won't choke that turbo. Yeah, well you're also forgetting the VW heads flow like ***.

That turbo will run out of breath around 5K more than likely.

ninjaturtleEG

^^he has the flange.

Yeah i thought about the higher efficiency of the honda engine....is there any porting i can do to the turbo? will a bigger exhaust help or hinder this situation?

da_dude

Pretty tiny turbo. Good for daily driving. If you're not planning on making big power then go for it.

post this on real homemade turbo.com .. delete the spaces.

You can make it work

Thanks guys, i'll go check out that site.

Dr1ft1ng0wns

Thanks for that site by the way....are you sure you didn't accidentally add the "real" in there?

rat city rex

It's because you went to the real site and didn't follow the rules. There is more knowledge on the real site then you will ever even grasp. So since you couldn't follow rules there your gona get a bunch of answers you don't want. You should just delete yourself from that site and move on.

Dr1ft1ng0wns

I'm trying to follow the rules now, i didn't see them at first cause i figured if there were rules they would be stickied, but they weren't. I guess I'll see how it goes.

So Is this the turbo your are referring to??



This thing is pretty small!

Dr1ft1ng0wns

I believe it is, looks identical.

I dont think that turbo is large enough to produce any sort of measurable gains on a D series. I know its fun to turbo something, especially when you get some of the parts for free; however, the power you stand to gain may not even be worth the investment. That turbo is the size of a baseball and will probably choke out on a D well before redline. The flow of a Beetle (aka horse ****) vs even a lowly D series is vastly different making this turbo a less than ideal match for the flow of your engine. If you want to try it, let us know how it goes...i wouldnt expect miracles

PS: You're going to want more than 7psi out of that thing. At that pressure, you may as well insert a hair dryer into your intake pipe. If you can push this thing to 16-20psi (which will happen almost off idle), then you stand a chance of having at least some boost by the time you near redline. Prepare to watch boost plummet once VTEC hits. At any rate, it should add a bit more zip in the lower revs

Another small turbo honda eh? Get a good BOV that wont get annoying...you are going to hear it ALOT!

Dr1ft1ng0wns

it doesn't have vtec, and how would i go about pumping up the boost? can i just adjust the rod on the internal wastegate? or will i have to weld it shut and run an external? and I'm not expecting miracles, just maybe 50 or so hp lower then 6k.

Schister66

You can get a boost controller and put it inline from the vacuum port on the compressor of the turbo to the wastegate. That's how all boost controllers are run. That will allow you to run a higher boost level than it was original set to. There are inherent problems with this small of a turbo on a higher flowing engine with a boost controller that you need to be wary of. You may have boost creep issues since you're pushing a good amount of air through a very tiny wastegate hole. I dont think you'll have to run an external gate to control it, but its a possibility. As for power creation, you'll certainly notice a large gain in hp and tq in the lower rpms, but it will most likely diminish substantially by redline. By the sounds of it, that's fine by you. I think this will do what you're wanting...your goals are reasonable.

We need to get TheShodan's input...

Dr1ft1ng0wns

so how much of a problem can boost creep be? I'm guessing that if it goes above what the map can read, then it will lean out and cause all sorts of issues? Why doesn't the bov catch the higher boost and open up? and as for the parts list, so far i know i need some dsm injectors, use the stock fuel pump, bov, header of some sort, and some sort of engine management. I have no clue what to do about engine management. any suggestions?

Just buy a T3 57trim Garrett or aftermarket Precision stay away from the cheap non brand ones.. Gotta get something bigger then a T2.
